Summary: This study investigates the association between intermittent fasting and age-related macular degeneration (AMD) in the older adult population. It finds that intermittent fasting, particularly skipping breakfast, is significantly associated with a reduced risk of AMD in representative older adults, especially in individuals with a younger age, obesity, and urban residence.

Summary: Global epidemiological studies highlight the significance of chronic non-communicable diseases like atherosclerosis and metabolic disorders in premature mortality and morbidity, with cardiovascular diseases such as ischemic heart disease contributing significantly to the global disease burden and socioeconomic health costs. Research demonstrates a link between oxidative stress markers and major cardiovascular diseases, emphasizing the role of reactive oxygen and nitrogen species in conditions like hyperlipidemia, hypertension, and diabetes. In vivo redox biomarkers are discussed for their clinical relevance, while the potential prognostic value and limitations of these markers are critically examined.

Summary: Reactive oxygen species (ROS) play a significant role in various biological systems, acting as both a cause and a consequence in liver-related metabolic disorders such as steatohepatitis. Medications targeting ROS formation and reducing ROS levels have gained interest as a therapeutic approach. Nanotechnology, utilizing nanocomplex systems as efficient nano-antioxidants, offers enhanced antioxidant delivery to the target site and improved accuracy, making it a promising avenue for efficient therapeutic interventions in oxidative stress-related liver disorders.

Summary: This study investigates the role of acidic bile salts in activating NOTCH signaling in oesophageal adenocarcinoma (EAC). The researchers found that there is a crosstalk between APE1 redox function, reflux-induced inflammation, and DLL1 upregulation, which promotes cancer cell stem-like properties in EAC. The overexpression of APE1 and DLL1 is associated with poor overall survival in EAC patients.

Summary: Arsenic contamination in drinking water is a global public health problem. Selenium deficiency is associated with an increased risk of arsenism. This study found that low Se status impairs redox homeostasis, leading to increased As retention in erythrocytes and subsequent phagocytosis by splenic macrophages, resulting in increased inflammatory response.

Summary: Recent studies have shown that factors such as anti-retroviral therapy, co-infections, immune system alterations, and microbiome perturbations contribute to HIV-associated inflammation, potentially increasing the risk of age-related morbidities in people living with HIV. Understanding the mechanisms that exacerbate inflammaging in people with HIV may lead to improved intervention strategies, ultimately extending both lifespan and healthspan.

Summary: Research suggests that HIV-infected individuals have elevated levels of inflammatory cytokines following exposure to LPS or ssPolyU. Estrogen exposure may enhance innate immune activation in HIV-infected individuals. Plasma markers show higher levels of immune activation in HIV-infected individuals, positively associated with in vitro responsiveness to estrogen and LPS.

Summary: This study demonstrates that human platelets and megakaryocytes contain an important antimicrobial peptide called hBD-3, which can be detected on the surface of activated platelets as well as in platelet derived extracellular vesicles (p-EVs). The presence of hBD-3 in p-EVs can contribute to platelet activation and endothelial dysfunction, potentially creating a pro-thrombotic vascular microenvironment.

Summary: This pilot study aimed to determine proper diagnostic testing for detecting chronic disease in COVID-19 long-haulers. A convenient sample of nine patients were evaluated based on symptoms, providing sonographic imaging data, blood samples, and completing the EQ-5D questionnaire. The study found that renal sonography, flow cytometry, and dynamic sonographic assessment may hold promise for guiding the treatment and surveillance of these patients.

Summary: This article reports the emergence of SARS-CoV-2 escape mutations during bamlanivimab therapy in a phase II clinical trial. The study found that treatment-emergent resistance mutations were more likely to be detected in the low-dose treatment group, and participants with resistance mutations had higher respiratory tract viral loads. The results also showed the rapid replication of the virus after the emergence of resistance mutations.

Summary: This study aims to better understand the association between characteristics of COVID-19 patients and their outcomes. It found that risk factors such as age, Hispanic ethnicity, elevated baseline creatinine or troponin levels, baseline lymphopenia, presence of infiltrate by chest imaging, and high SARS-CoV2 viral load were associated with prolonged hospitalization or death. Female sex was the only risk factor associated with post-acute sequalae of COVID-19 (PASC). The findings provide important insights for patient management and prognosis improvement.

Summary: Combining screening techniques, such as sonographic aortic calcification quantification, measurement of aortic intimal thickness, and monocyte laboratory values, provides improved diagnostic detection of cardiovascular disease (CVD) risk compared to computed tomography (CT) calcium scoring. The combination of sonography with flow cytometry shows promise as an alternative method for assessing CVD risk.
